1

Where testes are located

Scrotum

2

Where sperm maturation takes place

Epididymis

3

tube, empties into ejaculatory duct

Ductus (vas) deferens

4

Runs length of penis

Spongy Urethra

5

liquid in which sperm leaves body

seminal fluid

6

secretes milky fluid, plays role in sperm activation

Prostate

7

External genitalia

Penis

8

Counterpart of testes, produce oocytes, estrogen, progesterone

ovaries

9

copulatory organ, birth canal

vagina

10

where egg is typically fertilized

fallopian tubes

11

Loose fold of skin circling penis (foreskin)

prepuce

12

Function of the urinary system

-Get rid of wastes
-Acid/base balance
-Electrolyte balance
-Homeostasis

13

Kidneys

-Homeostatic organ
-Maintain water & electrolyte balance
-Excrete nitrogenous waste

14

Ureters

convey urine from kidney to bladder

15

Brown temporary storage container for urine

Urinary Bladder

16

Cream, male transport of urine/sperm, female is shorter, empties/releases bladder

Urethra

17

Blood circles through and is filtered

nephron

18

Secondarily important site of reabsorption

Distal convoluted tubule

19

Voiding/emptying bladder

micturition

20

inability to control sphincter (part of urethra)

incontinence

21

Mitosis

-2 identical diploid cells
-1 cell division
-Body Cells

22

The same between mitosis and meiosis

-DNA replication
-Prophase, metaphase, anaphase, telophase

23

Meiosis

-4 haploid daughter cells (not identical)
-2 consecutive cell divisions
-Gametes

24

Presence of puss in urine

pyuria

25

Red blood cells in urine

Hematuria

26

Hemoglobin in urine

Hemoglobinuria

27

Crossing over, genetic variation

synapsis

28

tetrad

groups of 4

29

2n, 46 body cells (2 sets of chromosomes)

Diploid

30

n, 23 gametes (23 chromosomes)

Haploid

31

Primitive stem cell

spermatogonium

32

Will undergo meiosis, puberty

primary spermatocyte

33

Haploid cells, product of meiosis, not functional (end of meiosis II)

spermatids

34

Process that takes away excess cytoplasm and turns into motile, streamline sperm

spermiogenesis

35

haploid gametes, formed in testes

sperm

36

Providing nutrients for developing sperm

sustenacular cell

37

Results in 1 ovum, 3 polar bodies

oogenesis

38

Primitive cell (beginning) in developing female fetus

oogonia

39

Form before birth, lifetime supply, in stage through infancy and puberty until puberty

primary oocytes

40

After puberty starts, produces estrogen

primary follicle

41

Found in mature vesicular follicle of ovary

secondary oocyte

42

Produces estrogen, major hormone

vesicular follicle

43

In uterine tube shortly after sperm penetration, not self moving, larger than sperm

ovum

44

polar bodies __________ because there is not enough DNA or cytoplasm to sustain them.

Disintegrate

45

Growth of person (cells), repair

mitosis
